Setup, Compatibility & Care
To begin, ensure both handles are fully charged using the provided glass charger or base stand. Download the Sonicare app from your mobile app store and enable Bluetooth to pair the brush with your device. To maintain hygiene, rinse the brush head thoroughly after each use and allow it to air dry. Replace the A3 All-in-One brush head every three months, or sooner if the bristles appear frayed. The handles are water-resistant but should not be submerged in water for extended periods. When traveling, ensure the handles are switched off and securely stored in the provided travel case to prevent accidental activation.
